The Quantum M2 distinguishes itself through its aerospace-grade precision machining, unique features like barrel linear expansion rings for heat management, and a superior rail-to-receiver locking system using alignment pins. Its integrated buffer system and Zero Trigger contribute to an exceptionally smooth and low-recoil shooting experience.

What are the key internal components and materials used in the Blackout Defense Quantum M2?

The bolt carrier is constructed from 8620 steel, while the bolt is made from shot-peened 9310 or Carpenter 158 steel. These components are high-pressure tested and individually inspected for micro-cracks, ensuring high reliability and durability.
